Binary graft copolymerization of thermosensitive, 2-(dimethylamino) ethyl methacrylate (DMAEMA) and pH sensitive acrylic acid (AAc) monomers onto polypropylene (PP) films was carried out by two individual step using a 60Co gamma radiation source. The grafting technique is a simple green process (additive free) that occurs at room temperature and has many advantages compared to conventional chemical methods The PP film was initially modified by grafting of DMAEMA, through a direct method, DMAEMA-g-PP film obtained was subjected to subsequent radiation grafting reaction of AAc for pre-irradiaton method, to give (DMAEMA-g-PP)-g-AAc. The optimal conditions, such as reaction time, reaction temperature, monomer concentration, and dose were studied. The aim of this work was to investigate the factors that affect the grafting yield of DMAEMA and AAc and also to characterize the grafted films by analytical techniques such as the swelling behavior, DSC, TGA, contact angle, and FT-IR. The grafting yield was determined gravimetrically.
